While those might seem like predictions in retrospect, Keenan told Zane Lowe that's only because history repeats itself.

"I feel like we're going to go through a lot of changes," Keenan said. "We're going to go through a lot of growing pains — and not all of us are going to make it through those growing pains. That's the hardest part, as a human being, to really grasp: that you might not be a part of what happens over the crest in that new valley. You just might not be there because you didn't pay attention to the basics. You didn't listen to the wind, you didn't smell the air ... simple things."

Keenan previously suggested that he was looking inward when it came to many of the lyrics on Fear Inoculum. Given the 13-year gap between Tool albums, the singer said the band was experiencing a "crippling fear" that its comeback record would fail and all its work had been for nothing.
